This is really a one shot deal I think,
We know from AI each season that there are hundreds of delusional people who think they have the sound and the look to make it big when everyone watching cansee they clearly don't.

You're probably right. I mean, once the "hoax" is revealed, they'd be hard-pressed to get people to try out for "Superstar USA" and actually think they were going to be stars. Sort of like the Joe Millionaire show.
